This means that one synchronous state transition map follows one site. For example, the dominant hand.

A second synchronous map follows a second site. For example, the secondary hand.

If you pause my video, each energy state node shows the possibilities, at that moment in time, for the site. An object can be thrown into the site, increasing it's number by one. An object can be thrown from the site, decreasing it's number by one. An object can be kept and thrown to another moment in time.

Option #1
If I then throw in a 4th ball, I can perform (8x,6) and then repeat (0,8).
[1111] energy state is now reached. "4 balls juggled in one hand".
Option #2
Alternately, I can perform (6,8x) and then repeat (0,8).
[1111] energy state is now reached. "4 balls juggled in one hand".
